Bee was very clear about what we could expect from the apartment, and what she expected from us. She and her father communicated with us regularly and let us know that we could contact them at any time if we had any problems at all. Pimon was particularly helpful, even going so far as to offer us a ride to the airport at 4am!
The apartment itself was exactly what I expected based on the description - it's very nice and clean, and the air-conditioning works perfectly and quietly. The view from the apartment itself is nothing special, as it looks out onto another building, but that fact helps to keep the apartment cooler and quieter, I think. And there's a great view available for anyone with access to the building from two terraces at either end of the 16th floor (worth checking out if you stay here!).
The only slight drawback is that because it's a fairly small space, if you are two people it is a bit shy on storage space for your possessions - you might have to get a bit creative if you want to keep the place neat.
Overall, we were very satisfied with the apartment, and our hosts made us feel very safe, secure and comfortable - I'd recommend it to any singles or couples looking for a place to stay in Bangkok.
